FASTENING. DEVICE.

Application filed November 1l,` 195.

To Yf/Z- whom t may concern:

Be it known that I, CHARLES E. LOMBARD, a citizen of the United States,residing at East llilton, in the co-unty of Franklin and Sta-te 'ofMaine, have invented a new and useful Fastening Device, of which thefollowing is a specification.

This invention relates to a fastener for covers such as used, forexample, upon milk cans and the like, one of the objects of theinvention being to pro-vide a simple and eilicient fastener which can bereadily shifted to position to connect the cover to the can and whichcan be quickly adjusted to bind the cover securely on the can, thus toeifcctually seal it.

A further object is to provide a fastening utilizing nuts for tighteningthe same, the nuts being so mounted that, when turned in 011e directionfor the purpose of tightening the fastening, they will direct thefastoning into engagement with the neck portion of the canso that thefastening' will be successively shifted to engaging position and thentightened during one operation of screwing the nuts.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings z--Figure l is a side elevation of a portion of a canhaving a cover secured thereon by means of a fastening such asconstitutes the present invention. Fig. 2 is a plan view of thestructure shown in Fig. l. Fig. 8 is a section on line A-B Fig. 2. Fig.4 is a detail view of one end portion of the fastening bolt.

Referring to the figures by characters of reference l designates theneck portion of a can the mouth of which is surrounded by a band 2 whichcan be secured there-to in any desired manner and which forms an annularshoulder 3 at the lower edge thereof. If preferred, this band can bemade integral with the can.

The cover #i is adapted to be inserted into Specification of Letterslatent.

the mouth of the can groove 5 in the lower face thereof for thereception of the upper edge portion of the can. @utstanding from theperipheral portion of the cover are ears 6 each of which has a bore 7extending therethrough. In each bore a bolt 8 is mounted for rotationthere being a segmental head 9 at the lower end of the bolt while theupper end thereof is serewthreaded, as at l0 and is engaged by a wingnut ll. This wing nut has an annular groove l2 in the lower end portionthereof and in this groove is seated an eye 13 formed at the upper endof a spring iinger lei which is soldered or otherwise fastened to theear 6. Extending downwardly from the outer end portion of the ear is astop finger l5 designed to limit the rotation of the head 9.

In app-lying a cover and securing it by means of the fasteningconstituting' the present invention, said cover is placed in posi tionwhile the heads 9 are in contact with the stop fingers l5. After thecover has beenproperly positioned, the nuts 1l are successivelytightened. As each nut l1 is turned to the right for the purpose oftightening it, its frictional engagement with the threaded bolt l0 willcause said bolt to turn therewith and to move its head 9 into positionunder the shoulder 3, the convex face of the head coming against theside of the can. Continued rotation of the nut will result in forcingthe head against the shoulder so as to causethe cover to be pulledtightly down onto the mouth of the can, thus sealing the same. After allofthe fastening devices have thus been tightened, the cover will besecurely held in position. By turning each nut in the oppositedirection, it will be held to the ear 6 by the spring lli so thatrotation of the nut will result first in the downward movement of thebolt 8 so as to disengage the head 9 from shoulder 3 after which thefrictional engagement of the nut with the bolt will result in the headbeing' swung outwardly against the stop iinger 15.

From the foregoing it will be apparent that but one operation isnecessary either to apply or to disengage the bolt from the can. Theiirst or applying operation is effected by the rotation of the nut inone direction to successively move the head 9 into engagement with theshoulder 3 and to tighten the head thereagainst, while the opand has acontinuous eration of releasing the covernierely results in thecontinuous rotation or the nut in one direction to successively shift itout of engagement with the shoulder 3 and to then swing it back againstthe linger 15.

Importance is attached to the fact that the cover can be placed in anyposition desired on the can and the heads 9 will always move properlyinto engagement with the shoulder 3 when shifted in the manner. pointedout. lt is not necessary to provide any special recesses for thereception of the heads 9.

The combination with a can having an annular shoulder, of a coverdetachably mount ed on the can, outstanding ears thereon, bolts mountedfor rotation in the respective ears, each bolt having a segmental headat its .lower end, a nut threaded upon the upper Copies of this patentmay be obtained for end of each holt, means for holding each nut againstthe top of the ear, each nut consti tuting means Vfor successivelyswinging the head ot' its bolt into engagement With the shoulder and fortightening said head against the shoulder, thereby to bind the coverupon the can, and a stop depending from each ear :for limiting therotation of the adjacent head away from the shoulder, said head beingmovable into engagement with the shoulder at any desired pointtherealong.

lntestimony that I claim the foregoing as my own, l have hereto affixedmy signature in the presence of two Witnesses.
